Change-Based Testing in a Yarn-managed monorepo Change-Based Testing in a Yarn-Based Monorepo In the world of software development, especially when working with large projects, efficiency is key. One approach to manage large codebases effectively is by using a monorepo, where multiple projects are stored in a single repository. Yarn, a popular package manager for JavaScript, provides powerful tools to manage such monorepos. One of the standout features is the ability to run commands across multiple workspaces with precision and efficiency.
